Apparatus for purifying exhaust engine-gases.



feedipipe 13 connects with the underside of the tank and by means of a union 13a with a Tshort section oi pipe 9", which terminates in the seat- 9 in the top obody 1. This feedpipe is provided near the tank, or any other convenient part of it, with a needle valve 14"of well known construction, for regulating the amount of liquid supplied to the body 1 or to the pipe section`9b. By means of valve 14 the flow of liquid may be shut oft' incase of repairs to any of the parts in `the body 1.

y body casing 1 and provided-with a'w'iping arm 5" of the proper length to strike orliinpinge upon the lower end of thehandle 9d of the spring valve and slightly open the saine to permit the flow of'a small amount of purifying liquid into the current of foul gas. The blades .of the revolving vbutter-ily wheels will strike and spray the liquid as it falls into tlie body and the current of gas will carry the spray into the strainers and keep them `wet with the purifying and deodorizing liquid. The strainers, thus kept wet, with liquid, will purify and deodorize the gas as it is passed through them. It will be noted that the valve will be opened at every revolution or' the butter-fly wheel and will be immediately closed until again opened by the long blade 5' or the arm 5l.

When the engine has been standing idle for sometime, the feed-pipe will become filled with liquid down to the valve, and

therefore, Awhen the engine starts more liquid will be supplied.v This will be advantageous because at that time the exhaust fumes, or gases, are apt to be at their Worst, and consequently require `more thorough purification.

My apparatus can be easily and quickly installed and takes up very little room in a vehicle. The construction being simple there is nothing to get out of order but what can be repaired at little expense. The needle valve being once set to regulate the flow of liquid the operation is practically automatic.

The purifying liquid is vof such acharacter thatit will deodorize the gases but will not eat or corrode the parts of the apparatus. l Y

vThe weighted blade 5 Will naturally fall to the bottoni of the body casingl when theil engine is at rest, permitting theball valve to be closed, so that no liquid can escape until the engine is again running. I

Having thus described my invention, what I claim, and desire4 to secure by Letters Patent, is

l. The combination with an internal combustionvengine, of'a'n exhaust purifier, com- Q; The combination with an internal co1n' bustion engine, of an exhaust purifier. coni- Iprising a body or pipe section, having a transverse porous strainer, a supply pipe t'or puriiyi-ng liquid opening into the body 1n Jfront of the strainer, and having a valve,

, and means in thebody in the path of the current of exhaust gas for opening the valve, wherebysuch means may be moved by the current and the valve intermittently opened to supply liquid to thevcurrent of gas before passing through the strainer.

3. The combination lwith an internal combustion engine, of an exhaust purifier, comprising a body casing, having a transverse strainer, a supply pipe for purifying liquid opening into. the body in front of the strainer, and having a valve, a butterflywheel or fan mounted in the body casing neai' said valve, and having an extended arm oi' blade adapted to open the valve when .said i'vheel is turned by the current of exhaust gas, for supplying purifying liquid to said current ot' gas before .passing through the Strainer. c

4. r1`he combination with an internal coinbustion engine, et' an exhaust purifier, coinprising a body easing, having a transverse strainer, a liquid supply pipe having a valve at its opening into the said body, a butterflywheel, having one blade extended and weighted at its outer endv and adaptedI to open said valve, and nieans in the easing for directing the current ot' gas against the upper -part of said vwheel for turning the same. y

The combination with an interna-loom- Iiustion engine, of an exhaust purifier, coniprising a body casing, having a transverse strainer, a liquid supply pipe having a valve, a butterfly-wheel having an arm or blade adapted to open the valve, and an upwardly inclined plate for directing the current of gas against the uppeipart ot' said wheel to turn the saine. c

(i. In an exhaust purifier casing, a straine'r arranged in the path of the gas current, a. liquid supply pipe having an opening and valve seat in the top of the casing, a ball valve resting on the seat and a butterfly wheel having an arni orblade adapted to impinge on tio ball for raising the saine when the Wheel is turned by the current of exhaust gas, all in combination, substantially as described.
